Problems solved by technology

However, the photoelectric sensor has high requirements on the printing surface, and it cannot be well adapted to the complex shape of the printing surface.
[0006] According to the above, in the coding of some occasions, the coding device and the printing surface need to be in contact and there is relative motion to complete the coding. However, the complex contact surface and smooth surface will cause slippage. Therefore, it is necessary to provide A coding device and a coding control method capable of avoiding slipping or compensating for slipping

Embodiment 1

[0034] Figure 4 It is a functional block diagram of the synchronization unit of the first embodiment. The synchronous unit 23 includes a synchronous motor unit 238 and a synchronous pulse adjustment unit 239. When the roller 64 rolls, the synchronous motor unit 238 is driven to rotate, and the synchronous motor unit 238 outputs the synchronous pulse signal Ss0 to the synchronous pulse adjustment unit 239 according to the rotating speed, and the synchronous pulse adjustment unit 239 Detect whether the roller 64 slips according to the received synchronous pulse signal Ss0. When slipping occurs, the estimated nozzle moving speed Vr is obtained according to the set algorithm, and a synchronous pulse signal Ss1 is generated and output according to Vr. When slipping is detected When the state ends, the synchronous pulse adjustment unit 239 resumes outputting the synchronous pulse signal Ss1 according to the synchronous pulse signal Ss0 of the synchronous motor unit 238 .

Abstract

The invention discloses a code spraying control method for a code spraying device. The code spraying device comprises an acceleration sensor. The method comprises the steps that acceleration information of an acceleration sensor unit is obtained, a synchronizing signal is dynamically generated according to the acceleration information, and the code spraying speed of the code spraying device is synchronously controlled according to the synchronizing signal. After the technical scheme is adopted, the code spraying device can avoid the slipping phenomenon or compensate slipping, can automaticallyadapt to complex appearance characteristics of the livestock carcass skin and solve the problems of slipping due to wet skin in the process of spraying codes on livestock carcass skin, is good in marking effect and can print two-dimensional codes on the livestock carcass skin, so that pork, beef and the like can be traced back in the circulation link, and food safety is guaranteed.

Description
